I have to agree with Sooty57 - wait on this one until the next version (this review is of v1.0.1). While it is a really nicely featured and great looking calendar, any time you revise an event - any edit at all, you get HTML displayed instead of formatted content. I mean, who enters their content perfectly the very first time?
These issues have been addressed in the new version, as well as lots of new feature additions. Enjoy! :)
